i've made this bass synth in reason - i think it's got potential to be rough,
i'm going to keep developing it, i thought i would share it as these sounds
can be hard to make in Reason and it may be helpful for anyone struggling
to make one or for someone who might be able to improve it and use it.

It's 2 detuned sine waves in Subtractor with a SQ wave LFO on filter 1, the speed of
which can be automated for 'wobble'. the mod wheel knocks off a lot of the
programmed modulation. you may want to take off the portamento, depending
on your melody.

then there is chorus/flanger & unison to add depth and two Scream distortion units
that mangle the sound - changing the setting of these really alters the sound.

the 4 LFO outputs of the two Malstrom units control the parameters of the Scream
distortion to add variation to the signal/amount of distortion.

a little bit of reverb to give it scale. compressor and maximiser and that's it.

let me know if you play with it - would be interested to hear results.

i've upped the .rns and .cmb file as a .zip and hopefully it's backwards compatible
as made in Reason 5 (PS. THIS IS NOT A RICK ROLL!)
